I had to wait with my son until he was about 6 weeks old in order for his OS Rumparooz that we only bought to fit. We went through way too many disposables with him, so this time When DD is due here in May we are starting from the time we get home from the hospital.

my dd was a month and a half. we had to use cloth because pampers baby dry had burned her bum really bad.
i started with the gerber prefolds my mom had gotten me when i was pregnant. i had no covers or any clue on how to use cloth(i would tie up the ends together with rubber bands so the prefold would not fall apart lol) . i started researching and couldn't believe all the amazing and easy ways there was to cloth. needles to say i stuck with it and we are going 6 months and strong into cloth. i love it.

We started at birth. With #1 we didn't know a lot and used the gerber PFs we'd been gifted which were awful. We ended up using sposies we'd been gifted (I planned to donate or regift but with our learning curve I WAS glad to have had them) while we figured out something manageable, which ended up being flats and BSWW until I started sewing diapers. Even in sposies I never let them sit in pee or change on a schedule, I change every time they go. We counted 32 diapers a day with #1 on average. The cost savings and trash production just cemented how much we wanted to CD.

With #2 we CD'ed from birth and didn't touch a sposie till 14-15 months when we did an extended camping trip with no good way to wash diapers on the road. People kept telling me my stash was enough and that #1 was an abnormal pee producer so I had a smaller stash and immediately regretted it. DD went through 30+ fitteds/flats a day as well. This time I'm planning a rather large stash and we'll be CDing from birth again, hopefully a bit lower stress than the prior 2 tries.
